FREE CER Principles and Maintenance Questions and Answers
Which type of scope is used to identify soil or damage within a lumen that cannot be seen by manual visual inspection?
Explanation:
A borescope is specifically designed to identify soil or damage within a lumen that cannot be seen by manual visual inspection. It is a useful tool for inspecting hard-to-reach areas and ensuring thorough cleaning and reprocessing of endoscopes.
How should the airflow be designed in the soiled and decontamination areas of an endoscope reprocessing facility?
Explanation:
The soiled and decontamination areas in an endoscope reprocessing facility should be designed with negative pressure, meaning air flows into the area. Negative pressure helps prevent the spread of contaminants by ensuring that any airborne particles or microorganisms are contained within the designated area, reducing the risk of cross-contamination to adjacent spaces.
What is the term for reprocessing that begins more than one hour after the endoscope has been used?
Explanation:
Reprocessing that begins more than one hour after the endoscope has been used is called "Delayed Processing." It is important to initiate reprocessing promptly after use to minimize the risk of microbial growth and ensure the effectiveness of the cleaning and disinfection process. Delayed processing may increase the likelihood of biofilm formation and compromise patient safety.
What is the minimum number of air exchanges per hour recommended for the soiled and decontamination areas in an endoscope reprocessing facility?
Explanation:
The soiled and decontamination areas in an endoscope reprocessing facility should hold a minimum of 10 air exchanges per hour. This ensures adequate ventilation and helps remove airborne contaminants, maintaining a clean and safe environment for endoscope reprocessing activities.
What is the maximum recommended relative humidity for endoscope storage?
Explanation:
The relative humidity should not exceed 60% for endoscope storage to prevent moisture-related damage and microbial growth. High humidity levels can promote the proliferation of microorganisms and lead to corrosion or deterioration of endoscope components. Therefore, maintaining humidity below 60% helps ensure the integrity and effectiveness of the reprocessing process.
What does "IFU" stand for in the context of medical device reprocessing?
Explanation:
"IFU" stands for "Instructions For Use" in the context of medical device reprocessing. These are written recommendations provided by the manufacturer of a medical device, detailing the safe and effective methods for reprocessing that particular device. Following the IFU ensures proper cleaning, disinfection, and sterilization, reducing the risk of contamination and ensuring patient safety.
Which type of endoscope is considered the most complex?
Explanation:
The most complex type of endoscope is the flexible endoscope. Unlike rigid endoscopes, which have a fixed shape, flexible endoscopes have a flexible insertion tube that allows for greater maneuverability and access to various anatomical structures. Flexible endoscopes also typically have additional components, such as bending sections and channels for instruments, making them more intricate and versatile in their applications.
What may cause a blown endoscope during ethylene oxide sterilization?
Explanation:
Ethylene oxide sterilization of a flexible endoscope may result in a blown endoscope if the endoscope is not vented properly. Ethylene oxide gas can build up within the endoscope during the sterilization process, leading to pressure buildup and potential damage to the endoscope's components. Proper venting ensures the safe release of gas and prevents the risk of a blown endoscope.
What are three ways endoscopes can be used to meet patient needs?
Explanation:
Endoscopes can be used in various ways to meet patient needs, including routine screening for early detection of diseases, diagnostic procedures to identify conditions or abnormalities, and therapeutic interventions to treat or manage health issues. These applications highlight the versatility and importance of endoscopic procedures in healthcare.
What is the purpose of waterproof tape in endoscope reprocessing?
Explanation:
Waterproof tape can be used as a temporary solution to seal a leaking endoscope, ensuring that it can still be disinfected properly. It is not meant for permanent sealing or preventing water from entering the endoscope during reprocessing.
What does "deflection" refer to in the context of flexible endoscopes?
Explanation:
"Deflection" refers to the ability of the tip of a flexible endoscope to bend, allowing for increased maneuverability and access to different areas of the body during procedures. This bending capability enhances the scope's versatility and enables physicians to navigate through complex anatomical structures with precision.
